i Y IM This invention relates to ma seat or cushion member. It-has for one object to rovide a seat iii which ventilation is provi ed. An-V other object is to' provide a seat in which n forced ventilation is provided. i Another obb-.y

ject is to provide a seat which will comprise a cushionin element and which will readily ada t itse f to and constantly follow the con-` toi 'of the user. l

For some purposes it is advisable to make the sheets of rubber; for some purposes they should be made of sponge rubber,

- and for 4still other` urposesthey might be O0 made of material ot er than rubber such as fabric. leather or felt. `The means which separate"` the twoy sheets from each otherl for some purposes should be made of sponge rubber,but other material` might be used. Ordi- Il nary rubber, `felt ortleather might serve and all of thesechanges are within the contemplation of .our invention. .i

l The use and operatio'n` of this invention are `as follows t Since the upper and lower sheet which form .y

the cushion are perforated, air can pass through them in a vertical direction, and` since these sheets are separated and supported apart from each other by a plurality of supports such as the members C or F, air may circulate horizontally through the cushion and, of course, thus air may be drawn in l through either of the openings A1, B1, D1 or E, and'may pass out along the edge of the cushion or vice versa. Thus, when a user is sitting on one of these cushions or leaning agalnst one of these cushions, an air space 1s Il provided between himv and the seat or back rof the article of furniture which supports ,n

him, and thus at all timesvair may circulate yfreely about him. In addition to this, since the cushion is yielding and since the meml0 bers which separatev the two perforated sheets` are yielding, if the user shifts his seat or position, someof the members such as C and bers positioned apart from each other and out of alignment with the perforations of' said sheets, the exposed sides of said sheets provided with perforated fabric coverings the cushion remaining open and free to the air on its edges.

2. In combination in a seat, a pair of rforated sheets and sponge rubber memers interposed between the sheets, said sponge rubber members ositioned apart from each other and out of) alignment with the perforations of said sheets, the exposed sides of said sheets provided with perforated fabric coverings the cushion remaining open and freeto the air on its edges.

F will be additionally compressed, thus bringing the two sheets kcloser together and serving to force or expel air laterally. When the user again shifts his seat, the sheets which have been forced toward each. other are permitted to separate and .thus air is positively drawn or sucked into the expanding space between the two sheets which now expand under'the influence of members C or F once they are free to do so because of the shifting weight of the user.

In addition to the Ventilating effect, because` of the yielding and springyconstruction of the cushion, the device is constantly in a state of motion as the user moves or shifts his position, and where the cushion is used in an automobile this motion is increased due, of course, to the movement of the vehicle over the road, and so the device has a manipulating or massaging effect which prevents cramping and discomfort on the part 'of the user. v 55 The cushion of our inventionmay be used in any association and in any location and f' 1.
